Third seed Ons Jabeur of Tunisia dropped the first set before storming back Tuesday to defeat Czech opponent Marie Bouzkova 3-6, 6-1, 6-1 in the Wimbledon quarterfinals in London.
Jabeur not only clinched her first Grand Slam semifinal appearance but also became the first Arab or North African player -- male or female -- to reach the semifinals of a Grand Slam event.
The world No. 2 is the highest seed left standing in the women's draw. In the semis, she will face Tatjana Maria of Germany.
Fourteen of Jabeur's 27 unforced errors came in the first set, allowing Bouzkova to take control. But Jabeur broke Bouzkova's serve six times in nine opportunities and lost just two games the rest of the way.
Jabeur has yet to lose on grass this season. She won the WTA German Open in Berlin last month and played alongside Serena Williams in the doubles draw of the Eastbourne International, winning two matches before Jabeur had to withdraw while nursing a knee injury.
In an all-German quarterfinal match, Maria rallied to defeat Jule Niemeier 4-6, 6-2, 7-5 in two hours and 18 minutes. Maria, 34, became the oldest woman to make her Wimbledon quarterfinal debut.
"It was a really tough match," Maria said. "It's always tough to play against a German girl. I didn't know her really well. We never even practiced together. So it was something completely new."
Maria, ranked No. 103 in the world, saved six of nine break points and charged back from down 4-2 in the third set. She won three games to take a 5-4 lead, and after Niemeier tied it 5-5, Maria was able to save a break point during the 11th game and grab the win that put her ahead for good.
"When you are outside on the court sometimes it's really hard to change your tactics, and I had to change my tactics a little bit," Maria said. "I'm happy that I could do it. I mean, even that I was 4-2 down in the third set, I kept going and I kept fighting. That's what I did."
Niemeier scored more winners than Maria (39 to 26) but also committed far more unforced errors (54 to 37).
In Wednesday's other quarterfinals, Australia's Ajla Tomljanovic will battle 17th seed Elena Rybakina of Kazakhstan and 16th seed Simona Halep of Romania will square off against 20th seed Amanda Anisimova of the U.S.
